Protection hook connecting bodies

Abstract

The invention discloses protection hook connecting bodies comprising a middle body. Ringent hook bodies are arranged at the two ends of the middle body, the gravity center of a space quadrangle body composed of the middle body and the hook bodies falls into a sphere with the geometric center of the space quadrangle body as a circle center and the radius 1 / 8 of the sum of the length, the width and the height of the boundary dimension of the space quadrangle body. Other restraining is not required to be added among hook connecting units, automatic hook connection among the units can be achieved through throwing, integrity is good, a throwing area of the hook connecting bodies forms a porosity structure, water flow can be reduced effectively, and energy dissipation and erosion control effects occur. The range of the gravity center of the space quadrangle body is restricted, hook connecting ability among the hook connecting units can be improved, even though the hook connecting units are randomly placed, the hook connecting units are prone to connection, separation among the hook connecting units is more difficult, and therefore the protection hook connecting bodies can be widely used in beach shore protection, pier protection, channel protection, dams and other engineering construction.

Description

technical field [0001] The invention relates to a protective structure, in particular to a protective hook-connected body in which the components themselves can be hooked separately in the state of loose throwing. Background technique [0002] The past examples of waterway protection projects show that the destruction of the beach protection or bottom protection in the waterway protection buildings is one of the main reasons for the damage of the protection buildings and the instability of the beach and water. At present, most of the protection measures for the beach and the foundation sand body of the protective building from erosion are to use the weight of the beach or bottom protection body to maintain the stability of the beach or bottom protection. This kind of completely passive protection, under the condition of relatively high water flow, due to the pulsation of the water flow and other reasons, it is more common to cause local washing on the edge of the row or bet...

Problems solved by technology

[0003]With the development of engineering science and technology, more and more people began to study structural types that can improve beach protection and bottom protection damage. In the late 1980s, domestic water conservancy Han Yingguan of the Northwest Institute of Water Conservancy Sciences of the Ministry of Finance and others proposed a permeable frame with four sides and six sides, which has been well applied in revetment reinforcement, but there are still some deficiencies in practical application, which are mainly reflected in the following two aspects: (1) In actual use, the four-sided and six-sided permeable frame needs 3 to 5 binding and throwing due to the weak connection between the four-sided and six-sided permeable frames. However, the overall stability is still insufficient, and displacement occurs under the action of water flow, which reduces the protective effect. ; (2) The welding joints of the four-sided and six-sided permeable frame members are easy to corrode and crack, and the members are scattered, resulting in complete destruction of the structure
